Broken video file using hardware encoding

[Timofey_Z]

Hi everyone,

I was recently working on my project, it was a long video in 4k and a high bitrate, so the final render was supposed to weigh 70 gigabytes. I rendered it with hardware encoding and wanted to watch the resulting video, but about halfway through (the entire video is about 50 minutes), the video just got stuck and wouldn't play any further. I rendered it a few more times, changed the settings, at first nothing changed, but then I realized that if you reduce the bitrate, the size of the final video predicted by Premiere decreases and then the video plays further and gets stuck closer to the end. In addition, I saw that no matter what file size Premiere estimated in the render window, the file always ended up being 40 gigabytes. That is, the video played only as long as it fit into 40 gigabytes of information; anything that went beyond these limits simply got stuck. In this case, no rendering error appears, the rendering simply ends as expected.

Then I changed the render encoding settings to software encoding. And everything worked. Videos of any size play normally after rendering. 

So in the end I don't really have a problem, but I'm just wondering what's going on? What's going on with the render with hardware encoding enabled? Could it be my media player or the computer itself?

Thanks in advance!

With best regards,

Timofey Z

Hi @Timofey_Z -  Thanks for submitting your bug report. We need a few more details to try to help with the issue.
Please see, How do I write a bug report?

What are your system specs?

What type of media are you working with?

Sorry for the frustration.

Hi @jamieclarke 

My system specs:

CPU - Intel Core i5-14600K

GPU - RTX 3060Ti

GPU driver - NVIDIA

RAM - Corsair Vengeance (2 x 16GB, 5600 MHz, DDR5 RAM, DIMM)

Hard Drive - Samsung 990 Pro 2TB

My videos used in the editing are recorded in MP4, H.264, All-I, 4K, 4:2:2, 10-bit, 400 Mbps.

For rendering, I choose the same codec and the same resolution, turn on the box "Render at maximum depth", and also "Use maximum render quality".

Thanks in advance.

Hi @Timofey_Z - Do you have any effects you are using in your timeline?  Are you using any third party plugins or panels?  Do you have enough drive space when exporting your files?  When you say the file gets stuck can you describe what that means?  Do you have cuda set for your renderer in your project settings?

Hi @jamieclarke 

Yes, the scene involves effects and third-party MORGT's. There is enough space on the disk. There is enough space on the disk. Yes, cuda is set for rendering in the project settings. 

After rendering, I run the resulting video file in a media player (MPC-HC). Some part of the video plays without problems, and then the image just freezes. The timeline counter continues to work, and the video time goes by, but the picture does not change and there is no sound.

Hi @Timofey_Z - Have you tried uploading the video to youtube to see if it plays?  Have you tried VLC?

Have you tried changing your encoding settings to "Software"? You can find them under Video > More > Encoding Settings

What GPU driver do you have, Adobe recommends using the studio version when working in Premiere Pro.
